The distinct flavor and color of Empress 1908 Original Indigo Gin comes from the infusion of tea botanicals. No artificial colors or stabilizers are used in its creation - so while the flavor will last forever, its unique indigo hue will not. Fading of the natural color is accelerated by exposure to sunlight. We recommend that you experience each bottle within a year of purchase and store in a cool, dark place. A gin this beautiful is meant to be enjoyed at its best.
